Summary 06697: grdforce: Hangs after insert coin
Description Guardian Force hangs after insert coin with black screen since MAME 0.184
Steps To Reproduce
Additional Information Sea Bass Fishing was fixed in MAME 0.184:
http://mametesters.org/view.php?id=4454
MAME 0.185: https://github.com/mamedev/mame/commit/c1f721a2504383df297017bfac622a97e3b1c7f7
Update MAME 0.185: https://github.com/mamedev/mame/commit/28e287458e5000b7f9ea833251605526e40ab33e
Sea Bass explicitly wants a monitor mode bit to be 0 when screen is disabled from bios to game transition.

This fix has something to do with Guardian Force. Deleting the following lines in video\stvvdp2.cpp (line 6010) fixed the hang/black screen
// if(STV_VDP2_LSMD == 0) // same for non-interlace mode
// {
// if((STV_VDP2_HRES & 1) == 0)
// return STV_VDP2_DISP;
//
// return 1;
// }

That doesn't take Sea Bass Fishing feelings into any consideration.

Hopefully fixed forever.
